100 factorial asMethodConst

As continue to Marcus cool features around haltOnce I implement analogue of Dolphin ##() syntax.

Slice is inbox (18768). So it will be available soon.

Idea is to send message #asMethodConst to result of expression which you want to cache. At first call it will replace full message send node with result as literal. And following method call will use this precomputed value.
